echo is a php term. All the code in this pertains to the CannaDx… I doubt they will have gits for the pen software yet. If they did they would be rather silly.
This is source for a page from a PHP app. PHP is a server side scripting language, in this case running a MYDX page. Based on the page name ("strain-profile") I'd guess it's what you'd see if you were checking out the results for a particular strain online. Nothing much here...you can see the source for most any web page by right clicking on the page and then "View Page Source" (or similar, depending on your browser).
